1. 0 45 790 0 145 Launch, light engine at 75% T. Increase to 100% T. Rotate at a = 11° ( » 2g) until q = 38°.
             
2. 30 52 1850 11 565 q = 38°. Maintain q = 38°.
             
3. 84.5 144 5150 8 60 Shutdown. Pushover to a = 0°. Establish b = 0 and switch heading vernier to "·Y."
             
4. 95 170 5000 0 21 Micrometeorite experiment to "extend."
             
5. 168 250 4460 0 0.7 Peak altitude. Extend speed brakes to 20°. Maintain q= -5° until a = 20°.
             
6. 237 180 4950 20 14 Micrometeorite experiment to "retract." a = 20°. Maintain a = 20° until Nz = 5.0 g. Heading vernier to standby.
             
7. 279 83 4450 20 740 Nz = 5.0. Maintain 5.0 g until Hdot = -800 fps (i.e. until q has peaked).
             
8. 286 75 4050 16 850 Hdot = -800 fps. Pushover to a» 3° to maintain Hdot » -600 fps. Extend speed brakes to 35°.
             
9. 296 65 3600 3 1140 Abeam Cuddeback. Vector to High Key. Speed brakes as required. Engine master off.
             
10.           High Key - check flaps and "squat" circuit breakers in. Arm stick kicker.

NOTES:

1. q vernier will be set at 38°, a crosspointer will null at 20°.

2. Emergency Lakes: Hidden Hills, Cuddeback.

3. Flight Duration: Approximately 10 minutes.

4. Flight plan based on 58,300# thrust at 100%. Engine #110.

Total burn time - 85.3 seconds.

 Launch wt. = 34,600# Burnout wt = 15,500# Landing wt. = 15,300#

c.g. = 21.2 c.g. = 19.5 c.g. = 18.2

In-flight Jettison Check (accounted for in weights and burn time.)

 GROUND RULES FOR NO LAUNCH: 1. Radio, Radar or TM malfunction.

2. Malfunction of any SAS channel.

3. Malfunction of inertial platform.

4. Malfunction of Ball Nose.

5. BCS Malfunction.

 ALTERNATE SITUATIONS AFTER LAUNCH:
 
 
Failure
  
Action
       
1. Radio or Radar   Proceed as planned.
       
2. Total pitch damper

Total roll damper

(turn Yaw damper off)

Total yaw damper

Failure to ASAS

 (a) 0 - 35 seconds

Pushover to 2° a at 35 secs. Shutdown at 5150 fps. (Hmax = 150K).
       
    (b) 35 seconds - shutdown

Pushover to 2° a when failure occurs. Reduce to minimum thrust at 73 seconds (4200 fps), shutdown at 5150 fps.
       
    (c) After shutdown

Proceed as planned. Use 15° a for reentry.
       
3. Ball nose failure (a) 0 - 35 seconds

Pushover to zero g at 35 seconds. Shutdown at 5150 fps. Heading vernier to "·y."
       
    (b) 35 seconds - shutdown

Pushover to zero g when failure occurs. Reduce minimum thrust at 73 seconds (4200 fps) if necessary, to reduce maximum altitude. Shutdown at 5150 fps. Heading vernier to "·y."
       
    (c) After shutdown

Heading vernier to "·y." Use q = -5° for entry (dh = -25°).
       
4. Attitude (a) 0 - 35 seconds

Use 9° a at 32 seconds instead of 38° q, then proceed with 3a.
       
    (b) 35 seconds - shutdown

Same as 2b.
       
    (c) After shutdown

Proceed as planned (Heading vernier remains in standby).
       
5. Delayed engine light   Proceed as planned.
       
  INADVERTENT ENGINE SHUTDOWN:

00 - 43 sec. Delamar

43 - 49 sec. ------ (2400 fps)

49 - 69 sec. Hidden Hills (2700 fps)

69 - 73 sec. Cuddeback (3900 fps)

73 - Up Edwards (4200 fps)
